PROBLEM TO BE SOLVED: To provide a sash which dispenses with work for sealing between a cover member and a mullion, which can surely prevent a coupler from being seen from the outside on the occurrence of the heat shrinkage of the cover member, and which can prevent a gap closing member from being removed by mischief etc. SOLUTION: This sash 1 is equipped with the mullion 3, a transom 5, the almost L-shaped coupler 7 which is fixed to a side surface 3a of the mullion and an indoor side surface 5a of the transom 5, the almost U-shaped cross-section cover member 9 which is fixed to the indoor side surface of the transom 5, and the almost U-shaped gap closing member 11 which is fixed to the side surface of the mullion 3 and with which a gap between a side end surface 9a of the cover member 9 and the mullion 3 is filled; the member 11 is positioned inside the cover member 9; and at least a part 7a, which is to be fixed to the mullion, of the coupler 9 is positioned inside the member 11.
